The variation of gamma radiation intensity between 200 keV to 10.0 MeV was measured, in the period from June 28 to September 25 of 2017. These measurements were taken 25 meters above ground level in a tower in São José dos Campos, SP, Brazil. A minute interval was used from each point of measurements. During this period, there were weak and moderate rains with net intensity of 27 mm. The variation in temperature during this period was between 15°C and 32°C, reproducing a desert-like climate. By monitoring the gamma radiation it was possible to observe the arrival of cold fronts from Southern Brazil and the (day/night) cycles due to the greater or lesser amount of radon gas present in the region. The main feature of this work is that it indicates the dynamics of gamma radiation in a simple way according to the variation of meteorological parameters in that location, which is very important for environmental studies in the tropical region.

Keywords :

Gamma radiation; cold fronts; radon gas; meteorological parameters; weak and moderate rains; day/night cycles.
